I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
So, yeah, I *finally* got to the text on this page. (Play with Grimlock's tab, go back and pay with Starscream and Bee's tabs, play with Grim's tab some more, and then play with Cybertron's tab, back to Grim. Repeat a couple times, then just play with Grim for... way too long.)
Grimlock's weapon is described as 'a big Energon sword.'
Yeah, you know it is. It's totally why he's king.
*insert sword/penis joke here*
