thor negated juggernaut's influx of magical energy be creating a magic blocking vortex with a thrown mijolnir surrounding juggernaut.
then before the minute of separation was up, thor one shotted his helmet to pieces. at that point juggernaut was in a de-powered state, like the one he was before wwh. he was still strong but probably around thing level.
now on odin-
odin can just create a force field around juggernaut with a thought that would nullify his powers then power himself up to do physical battle. then its curtains for cain marko.
NOTE- odin's normal strength is like 70-90 tons, he can magically raise it exponentially but in times of peace he stays at normal levels to conserve energy. after all the odin force has to be re-charged.
without the use of his odin force...couldn't see Odin winning
imagine it would be still a good fight....Odin is no slouch in the physical department..remember he has absorbed the powers of his 2 brothers....
with full use of powers....bye bye juggs.....
couldn't Odin amp himself with Odinforce?
why would this not be allowed?
the only stipulation here is that it is a "slugfest", this means that Odin may not use his magic for any exotic effect but, he could always use it upon himself to pump up his physical stats to say ... WWH levels?
