Originally posted by psycho gundamThe power gem was meaningless in that battle, as Thanos was far too slow to hit Runner with... Anything.
not at alldumb drax was able to use his power gem even though he swallowed it, pip had his clenched between his toes, and the majority of the other users had theirs on their brows; it's location on you doesn't matter, you just have to will it to do something.
thanos also had the power gem so he should have been able to do far more than he showed, plus he already researched the gems from a cosmic repository of knowledge.
starlin was saving feats for ig imo
And unlike the power gem, the time gem requires conscious/precise thought to use properly -- a thought process Thanos was unlikely to enter while being blitzed to hell. When Runner stopped his onslaught in order to monologue, Thanos was able to gain the advantage because he was no longer getting pummeled, and was finally able to tap his gem.
