Given his character through out New Vestroia Arc, He's like the worst father i have ever seen next to Zenoheld and really didn't care much for him after he met his demise.

Like after i've seen how he was head of science research when they were experimenting something on Hydranoid, And back at home, When Mira demanded him about the lives of Bakugan while he decides to not answer her, I honestly thought he was just doing something for Spectra given that he is his firstborn son, Similar to between Alice and Dr. Michael Gehabich when Michael was evil and corrupted and Alice was under Masquerade persona working together for Naga until Masquerade accepted on why he shouldn't exist because he is Alice while Michael was used for Naga's abilities to enable it in battle with Dan and Drago.

But in this case no, He was just obsessed with research of making the most powerful Bakugan of the universe (Or likely Most powerful Bakugans given he said the same statement when he created Aluze for Lync and then using Spectra's saved data from Drago to create an ultimate machine until Helios volunteerly steps up to be experimented to turn into a Cyborg so he can claim that power with Spectra's agreement).

When Mira confronted him by asking where Keith is, He hesitates to answer, Which idk if he actually knew Spectra was Keith or not and tells her to just "Forget about him" and even when she was asking all in concern by holding his arm, He just roughly swings his arm to get her off him that causes her to roughly fall on the ground, Definition of terrible father.

Even when Lync was about to leave the Vexos by acquiring some datas about the weapon that will literally destroy all Bakugans, He gave some pep talks about his kids to which he was a bit on a daze to think. But during the near end of the final battle when he worked on the super alternate weapon for Zenoheld, He completely lost it like a typical mad scientist, Even when his own children begged him to come with them until he felt defeated.

Now of course i'll give him credit that he did saved Mira from the collapsing ceilings, But other than that all he did in his last moment before he actually died, It's just having one last look on his research which he discovered Bakugans at war which of course leads the events of war between Gundalians and Neathians and then dies along with Zenoheld and Hydron.

So yeah, that's all i can say. I can't imagine how whoever Spectra's and Mira's mother is, Would be so ashamed of him.

Have to be honest i never liked and always hated Professor Clay
