"We tried to achieve a balance between style and practicality."
— Fon Davis on Mouser Mecha Catbot
Mouser Mecha-Catbot was a lightweight robot built by Fon Davis which competed in every BattleBots competition that featured its weight class.
It was a pink dome-shaped robot with a flattened top, painted to resemble a cat. Its weapons were lifting forks, which lifted off to the side instead of upward like conventional lifters, a circular saw (which was blocked by the forks) and a rear spiked tail which functioned as an axe (for the 1997 US Robot Wars, the Long Beach event and Season 1.0, it had a saw at the rear of the body instead of the axe). Mouser went through numerous incarnations, starting with the original Mouser Catbot at Robot Wars in 1997. It then became Mouser Catbot 2001 for the Long Beach 1999 competition. After that, when Mouser took severe damage from Executioner, the robot was painted with a "cybernetic implant" for Season 1.0. This edition of the robot (as well as the Season 2.0 version) were called Mouser Mecha-Catbot. For Season 3.0, Mouser was renamed to Mouser Super Mecha-Catbot. For Season 4.0 Mouser was no longer painted with a "cybernetic implant" and called Mouser Classic Mecha-Catbot. Finally, for Season 5.0 Mouser was painted with hot-rod flames and no longer was armed with the saw blade. This edition was called Mouser Ultra Mecha-Catbot. Mouser achieved moderate success during BattleBots, making the Season 1.0 and 3.0 quarter-finals, but never got too far into a tournament.
In 2015, the chassis of Mouser Ultra Mecha-Catbot had Moebius' shell placed on it and fought Vlad the Impaler 2 and Sewer Snake's replacement Evil Plunger, but lost overall.
Mouser Mecha-Catbot even had its own theme song and CD, written by BattleBots music writer Eban Schletter and sung by Olivia Olson.
Mouser Mecha-Catbot would temporarily reside in Team Malice's shop, hanging on a wall, as seen in a May 2021 episode of the Skorpios Builder Blog[1]. It would be seen in a July 2021 episode of Tested with Fon Davis[2]. Fon Davis would later confirm in a 2023 Reddit AMA that Mouser is currently hanging on the wall at Fonco Studios[3].

Mouser Catbot 2001's first match was against Shrike. In the match, Mouser tried to flip Shrike, but couldn't due to the wide length of Shrike. Later, Shrike was hitting Mouser with its axe several times. Despite the axe not dealing damage on top of Mouser due its thin Lexan armor, Mouser suddenly stopped moving and was counted out. Shrike won the fight by KO and Mouser was now in the loser's bracket, where it faced Paranoid Android.

As Mouser got lifted by the piston, Gamma Raptor gets underneath Mouser, pushes it toward the rear of the BattleBox, bounces Mouser into a screw, and Mouser is flipped on its back. While Mouser struggled to self-right, Gamma Raptor pushed the flipped Mouser under the pulverizer and after several tense seconds of trying to relay the issue to the ref, Mouser was counted out. When the buzzer rang, the pulverizer continued to hit Mouser, even after the ref said to stop (much to Fon's anger). After two hits beyond the end of the match, Gamma Raptor won the fight by KO and Mouser was eliminated again.
Lightweight Royal Rumble
Mouser spinning in circles.
Mouser also participated the Lightweight Royal Rumble at the end of the tournament.

Season 4.0[]
Mouser Classic Mecha-Catbot vs. Slap 'Em Silly

Both bots are tossed on the killsaws.
Due to previously competing in Season 3.0, Mouser Classic Mecha-Catbot was allowed to skip the preliminary rounds of Season 4.0, where it faced Slap 'Em Silly. Mouser drives straight into Slap 'Em Silly, but Slap 'Em Silly dodges. Mouser tried to flip Slap 'Em Silly with its flipping arm, but no luck. Slap 'Em Silly tries to drive its spike into Mouser's back, but Slap 'Em Silly drives right up the dome of Mouser and Mouser starts using the tail. Slap 'Em Silly escapes and positions itself. The two robots meet, side-by-side, and begin to turn in the same direction. Mouser tries to activate the flipping arm a couple times, but Slap 'Em Silly wasn't on its arm. Mouser got its arm under Slap 'Em Silly and activates it, but doesn't do much of anything to Slap 'Em Silly. Slap 'Em Silly tries to drive its wedge under Mouser's rear, but again, drives over the dome and into Mouser's tail. While Mouser was hitting Slap 'Em Silly with its tail, Slap 'Em Silly was pushing Mouser forward. Mouser turns around and Slap 'Em Silly slides off. Mouser fires its arm and Slap 'Em Silly tries to take advantage of the vulnerable front, but Slap 'Em Silly's wedge is higher than Mouser's dome. Slap 'Em Silly drives up onto Mouser and Mouser tries to flip it, but it just pushes Slap 'Em Silly off instead of toppling it. Slap 'Em Silly keeps trying to get under Mouser. Mouser's tail was briefly stuck in the seam between the wedge and body of Slap 'Em Silly. Mouser drives over the killsaws and Slap 'Em Silly got its wedge front high-centered on the side of Mouser. Mouser got away and Slap 'Em Silly was back on the BattleBox floor. Slap 'Em Silly drives onto the top of Mouser again, but again, Mouser couldn't flip it. Slap 'Em Silly drives around and teases Mouser into activating the arm again. When Mouser does, Slap 'Em Silly drives up and got itself in the way of letting the arm come back down. As Mouser was trying to escape, Mouser was caught on the killsaws. Mouser continues to try to flip Slap 'Em Silly and Slap 'Em Silly tries to push Mouser towards the pulverizer, but neither robot were successful. Both robots were separated and both robots moved to the middle of the BattleBox. Mouser tries another flip and misses. As Slap 'Em Silly tried to get underneath Mouser again, Mouser drives around the killsaws and a small chunk of the pink shell was sent flying to the other side of the BattleBox. Mouser got two successive lifts in on Slap 'Em Silly and Slap 'Em Silly pushes Mouser onto the killsaws. Both robots were tossed on the killsaws and Slap 'Em Silly got its spike jammed into the slot for Mouser's spiked tail. Slap 'Em Silly pushes Mouser onto the killsaws again before the time ran out. Slap 'Em Silly won the fight on a close 24-21 judges' decision and Mouser was eliminated from the tournament.

Season 5.0[]
Mouser Ultra Mecha-Catbot vs. Tentoumushi 8.0
Mouser fighting Tentoumushi 8.0.
Due to previously competing in Season 4.0, Mouser Ultra Mecha-Catbot was allowed to skip the preliminary rounds of Season 5.0, where it faced Tentoumushi 8.0. Tentoumushi 8.0 won the fight on a 29-16 judges' decision and Mouser was eliminated from the tournament once again.
As of 2022, it is unknown if Mouser Ultra Mecha-Catbot participated the Lightweight Consolation Rumble at the end of the tournament. Even if it did participate, it wouldn't come back for the Lightweight Royal Rumble due to an incident with Nightmare in the heavyweight consolation rumble which resulted in all the rumbles getting cancelled.
