Despite saying that he won't help the Swat Kats fight Mutilor because they don't believe in violence, Captain Grimalken has no problem kicking one of Mutilor's henchmen in the face while he's going for a blaster.
When Felina crashes the Mirada into the control room of the Aquian ship, the Swat Kats, Mutilor, and all his henchmen aren't immediately sucked out into the vacuum of space.
Traag says at one point that the Swat Kats have destroyed their entire squadron of Miradas, thereby leaving the mothership defenseless. However, when the Turbokat flies into the ship's hangar, not only are there dozens of Miradas still visibly parked there, but the ship itself is crawling with henchmen to pilot them.
It's quite a long time between when Felina first climbs aboard the downed Mirada and when she plows it into the ship. Although she admits that flying the craft was difficult, this still doesn't explain why she didn't return to Enforcer Headquarters or try and signal the search party out looking for her.
The Turbokat isn't ready, so the Swat Kats waste time turning the tow truck into the Thunder Truck, which is then destroyed by Mutilor's laser without much effort. Then they go back and finish repairing the Turbokat. And the point of the Thunder Truck was...?
Mutilor: It is so refreshing to clash with true warriors. It is a shame I must destroy you.
T-Bone: Great shot, buddy!
Razor: Uh, uh! Lousy shot! I'll be buffing out the dings for weeks!
Although in this episode Swat Kats fought the aliens who wanted to drain their planet's water resources, the planet's actual name was never mentioned, so therefore, we don't know if this is Megakat City on Earth, or on some other planet, or in some other dimension.
This is Mutilor's first and only appearance.
The first and (unfortunately) the only appearance of Thunder Truck.
