The Gryphon Squadron had the easiest battle, hands down.
Lanterk decided to experiment on the Covenant out of his hatred for Danny. Unfortunately, his direct manipulation and direction of the entire room made that battle a very difficult battle to overcome.
But of course, Lanterk was busy and only spared the least of his attention to that room. To bear the great burden of fighting and gather data for everyone's fight, he left his strongest Pioneers with a specialized Throne to fight against Lynd. Against Cliff, Lanterk sent another with a specialized Skinsuit which contained his attempt to recreate a Nefilus Suit. The appearance of the rumored Phallium suits inspired Lanterk to force something, but while the study drew no clear success as it simply acted similar to the throne, the skinsuit was still considered among the strongest weapon he had.
