Lyain Kepper and his Heart of Victor did not encounter a true challenge until they had entered the third round.
The Rayvin and the Parnast were both formidable machines, and they certainly deserved to go further in the tournament, but it was undeniable that they possessed clear vulnerabilities.
As long as he exhibited enough patience and cunning, the Heart of Victor could eventually exploit their weaknesses and defeat them in a relatively clear and unambiguous manner.
The Zenomon Gamma was different. Though the mech did possess a number of weaknesses, none of them were easy to take advantage of. The axeman mech was too well-protected and also possessed the power to cripple the Heart of Victor in a single blow!
Combined with surprisingly adequate speed for such a hefty frame, the Zenomon Gamma presented a package that was stronger than the Heart of Victor in almost every parameter!
