Wow, things are starting to get interesting...
Yuki and Marito are back on the crew, Inaho got himself a helping hand among the Vers knights and Slaine's has to do a straight up duel with another Vers knight.
What are the odds against each other? Well:
The Tharsis: Very manuverable Kataphract with the ability to see into the future (apparently), allowing it to shoot with pinpoint accuracy through the gravitational anomalies caused by the overload of the Hypergate. Furthermore, it allows to predict if and where shots of the enemies are gonna land, making evasive manuvers significantly more efficient. Also helps with planning ahead, although it seems to be not perfect in the heat of the battle when confronted by a very skilled pilot (such as Inaho)
Weakness: Aside from its predictive abilities, it has no special abilities such as lasers, barriers or whatever, it has to rely on its 2x5 machine guns and the 2 blades. Also, switching between them in the heat of the battle would be hard since they are on the opposite sides of the shields, putting it at a disadvantage at short range when using the machine guns and at long range when having the blades "active".
The Herschel: Not much is known about it since the only time it was seen in "combat" was in the few seconds after the Deucalion shot its main cannons in episode 15. There it was seen holding some lance-shaped weapon in its right hand, Considering the distance between the battlefield and the location it was at, it is most likely a long-range type. It didn't seem to affect the battlefield too much though.
The special ability it holds is yet to be revealed, however it should have some ability that gives its pilot the confidence to have a shot at winning after seeing Slaine destroying that orbital base all by himself.
Toss in some opinions on what the odds would be ;)
