I love the five headed dragon because it is such a powerful monster that you can whip onto the field fairly easily. The plus sides are its high ATK/DEF (5000/5000), but the negatives is that it can easily be destroyed by a spell trap or monster effect. But the fact that it takes 5 dragons to make this monster can be difficult to accomplish. Luckily I've devised a strategy to summon some powerful monsters to the field very quickly.
This Dragon is used as a powerhouse to destroy practically anything it attacks.
Combos with other cards:
You can summon this monster with polymerization but I highly recommend using Future Fusion. Future fusion sends the fusion materials for this monster to your graveyard and summons the fusion monster 2 turns later. I take advantage of what dragons I send to the graveyard. My favorite combination is to send 2 red eyes wyverns and 2 red eyes darkness dragons to the grave + 1 other dragon. you can also send the white stone of legend (which will send a blue eyes white dragon to your hand).
Or a personal favorite: 2 redeye wyvern, 2 redeye darkness drags, and 1 blue eyes white drag. this sets up your next turn. if you don't normal summon or set, you can remove both wyverns from play to special summon both darkness dragons from the graveyard.
Then on your next turn you special summon the 5 headed dragon from future fusion, you have 2 red eye darkness dragons on the field. and the two darkness dragons can special summon 2 more dragons from the graveyard or your hand, and you left a blue eyes white dragon in the grave, giving you at least 4 powerful dragons immediately on the field in such short time.
you can also use "Dragon's Mirror" spell card to whip out a fast 5 headed dragon (or use future fusion to send 3 blue eyes white dragons to the grave and Dragon's mirror to summon blue eyes ultimate (and then get 5 headed a turn later).
Ways to counteract it:
It's pretty easy to counteract 5 headed dragon though. it does not defend itself from spells/traps/monster effects. And if you use future fusion, any card that destroys future fusion destroys your 5 headed dragon, faster than you could summon it.
Highest ATK/DEF, able to make some insanely awesome combos.
Might be hard to summon if you don't draw enough of the right cards and it can get destroyed too easily for the effort that might take.
Artwork and aesthetics:
The artwork is a five headed dragon but it does not look that great. Its accurate art but for such a powerful monster it could have looked better. Many weaker monsters have more time put into the artwork and look better.
