Warforged Fighter 2 (Dungeon Crasher Variant)/Barbarian 1/Fighter 4 (Dungeon Crasher Variant)/Barbarian X/Frenzied Berserker X

Feats:
1: Admantine Body
B: Power Attack
3: Destructive Rage
B: Improved Bull Rush
6: Intimidating Rage
B: Cleave
9: open
12: open
15: open
18: open

So this is really just for fun.  What you do is ask your DM if your Admantine can be Glass Steel (it might have a different name I didn't bother looking) because they're pretty much the same thing but, glass steel is transparent, then you say your internal component is Fruit Punch.  You end up getting a +18 on Strength checks while raging or frenzing to break objects before your actual Strength bonus.  To be honest you really don't have to go into Frenzied Berserker and that will free up 2 feats it's really up to you.  I just thought the idea was funny.

 

Also you need access to the shout spell (item possibly) for when you burst into the room.

OH YEAH! 

This build can also be used to make the Juggernaut from X-Men.  I was thinking about making an NPC battle with this build (maybe changing the race to human), a Tiefling Swordsage specializing in Shadow Hand especially Shadow Jaunt and it's variants (Night Crawler), a Warlock that happens to shoot his Eldritch Blast out of his eyes (Cyclops), a Human Sorcerer or Druid into the Stormcaster from Stormwrack (Storm), a Changeling Factotum/Chameleon (Mystique), and maybe some others that I don't feel like thinking about right now.
