I like the idea of him as a herald of Galactus. Sure, he's not flashy with range attacks and multiple options like Noh-Varr... but power cosmic +7 damage (4 regular, +1 for herald, +2 for CCE), PLUS getting to hit for that twice in a single turn (once with a free action with a "revenge token" and once with a regular action) makes him a CRAZY one-hit-kill machine.
Ulik is a great click, He's served me well over the years. I've found that the most fun thing to do with him is as follows: TK him next or close to an opposing character. Have Lockjaw, or another Transporter, equipped with double time. Ulik makes his attack, and when the action is resolved, use lockjaw to come in, pick up Ulik, and just run away. Hit-and-run tactics. Don't leave him in battle for too long, in fear of losing his rather short charge duration.
