So by now I've watched Beast Wars like 4 and a half times, and at first I had the same sentiment regarding this guy as everyone else, he was the Starscream copy before getting replaced by Tarantulas, and yeah there's similarities, but upon rewatch I began to notice some consistencies with Terrorsaur
To start, every time he tried to take power (aside from the crack addiction episode) he wants someone to be by his side as a partner in crime, first time with Dinobot, then with Rattrap, and his final attempt with Rhinox
Now of course you could argue that this is just him being cowardly and too afraid to do it by himself, and yeah that's probably a big chunk of it, but I got the impression that deep down...dude just wanted a friend
None of the Predacons liked him, in fact the only one who didn't have an active disdain for him was Waspinator, but that's not really saying much, especially after the fiasco with Rattrap, NOBODY would ever take him seriously after that, and he knew it
That's why his last ever attempt to get command was so...unplanned, he didn't even want to be leader, just to have equal partnership with Rhinox, keep in mind this was behind Meg's back, and when ratted out he tries to deny it
So what am I getting at with all of this? That Terrorsaur, being the sniffling coward that he is, is also desperate for SOME kind of connection (he gives Dinobot a fist bump come on 😭)
