I visited a shop and they had both of them for CDN 35$. Is there a difference between Superlink Shockfleet and Energon Mirage? Is he a good mold? I am asking this because I saw the Banzai-tron pictures and he look cool. At the same time I like Classic Grimlock's mold and the Overkill color look good.
This is such a random horrible comparison of figures that no one is going to even try to give you advice. Obviously just fucking pick one and buy it. Superlink to a universe mold!??! They are like apples and oranges
I would say Superlink Shockfleet (Energon Mirage) as well. You should still be able to affordably get Universe Overkill for a little while longer.
$35 CDN seems like too much to pay for Overkill anyway. He retails for $16 USD, and even after shipping, still shouldn't cost that much. Go for Shockfleet if you must (dunno his going price anyway) and try picking up Overkill from the Junkion section later.
Shock Fleet he's not too different from the US toy. in fact its just minor paint apps like the red patches on his shoulders that on the US toy their pink and maybe a few other minor things. Also as some one else pointed out you might be able to get overkill for less
Shockfleet is the nicer toy out of the two. He's twice the size and a lot more fun. Overkill is a nice toy, but I don't think he's a contender when the other choice is Shockfleet.
