Battling a Giant: Rage of the Gladiator's Tagon in Challenge Mode

Quick Brew Info:
A few days ago, on July 2, I had a comment from an "Anonymous" reader on my Rage of the Gladiator's Ixthid: Rank S in Challenge Mode post.
It said, "Nice video.  Now howd u get to Ixthid... I cant beat Tagon on challenge mode..."

I replied back that I would see about making a video of a Tagon battle in Challenge Mode, and here it is!

WARNING!  If you do not want to see an entire battle against Tagon in Challenge Mode, from Rage of the Gladiator, do no watch this video:


Thoughts:
In this battle against Tagon on Challenge Mode, I was using the Wii Remote and Nunchuk controls; and I only used the most basic combo, the Charge Attack.  In the match shown, I attained a "Rank: S".
