Raw strength. But no brains...well not a lot of it anyway. While none of the Dynobots can be described as "geniuses" Sludge hits the bottom of the ladder. That being the case, Grimlock doesn't trust him with weaponry. Seems as if someone always gets shot by accident. But when it comes to strength, Sludge there is no comparison. His armor is twice as thick as the other Dynos. so much so that Grimlock often puts him up front during assaults. Short of a fusion cannon blast, nothing has ever scratched him. He does carry a few scars though, from that time he accidentally shot Slag is his rear processor. Ah...the memories. Sludge was repainted from a TFTM Stcokade figures. A few declas, but other wise unmodified. More pics HERE.
