Gargadan is described as, "...a twisted abomination - a cruel experiment gone horribly wrong. He is a fusion of a lion, dragon, and snake. The lion head seems to be in charge of the others, directing the creature's actions. Each head has its own mind though, and sometimes disobeys."
CoffeeWithGames shows a full battle against Gargadan in Rage of the Gladiator's Challenge Mode, using the game's Wii MotionPlus control option.
CWG shows it is possible to get a "Rank A" in Challenge Mode without using any high level special attacks against Gargadan.
Rage of the Gladiator has you beating Greek mythology foes in sort of a Punch-Out style, except with magic.
NWR - "Rage of the Gladiator was one of the best hidden gems from WiiWare. A Punch-Out style fighter with various characters influenced by Roman mythology sounds like a match made in Heaven, and thankfully, it was! Now after three years, the game finally makes its way to the 3DS. While I do miss the really cool MotionPlus controls from the original release, the game still manages to be fun and charming in its own right."

"When I decided to take a chance and review Rage of the Gladiator, I truly had no idea what to expect. A lot of interesting games hit the eShop, and it is often difficult to tell from just a cursory glance whether or not they are worth your money. Upon booting up the game, I was pleasantly surprised to find it to be very similar to the classic Punch-Out!!, except with medieval monstrosities as foes, and a pronounced focus on Greek mythology. Developed and published by Gamelion Studios and Ghostfire Games, it was originally released back in 2010 for the Wii Virtual Console to high acclaim. Now available three years later for iOS, Android and 3DS, was it worth reviving or should it have died in the arena?"
If you own Rage of the Gladiator, have you finished the game's Challenge Mode yet?
