Here are the legendary Giants figures I have. All of the legendary characters have slightly better stats than their regular counterparts but otherwise have the same skills and upgrades.
Stealth Elf, Chill, Slam Bam, Jet-Vac
Not present from a complete collection of Giants Legendaries are: Legendary Bouncer and Legendary Ignitor.
Generally I'm not over fond of the legendary characters because they are only painted differently and don't have new poses, but a few look pretty cool like Jet-Vac. The gold and black make him look a bit more bad ass.
Blue and gold is a good combo I guess.
In some cases it looks good, in others it's kind of dull, at least to my eyes.
Slam Bam looks pissed.
Imagine four arms. Does the left upper know what the right lower is doing?
Hey there is a giant version of the bird with the gun.
There's a Jet-Vac in all the games except the first one (Spryo's Adventure) and the last (Imaginators). He must've been popular 'cause he's a main character in the tv show.
