No way would there be a physical fight, Lea would crush them.
Have to agree with that. Despite having some powers Even and Ienzo aren't really fighting types.
They may hold out a time against Lea with Even taking a defensive position shielding Ienzo who then attacks with long range abilities, but in the end Lea would eventually outmuscle them.
Would be interesting to see though which side Aeleus would take as he was shown there as well.
I would assume though he would team up with Even and Ienzo due to his apparent loyalty to Ienzo...and then Lea would most likely be in trouble.
I doubt he could win against Even, Ienzo and Aeleus as a team.
