Who is Linderman?

I think Linderman is some kind of age old god and that he is the reason that everything is happening. Like the people with powers are his way of creating a new world. Similar to what happened in X-Men, how that got their powers.

I share the same opinion, i really think he is Hiro´s father but in other hand it will be obvious so probably isn´t..

I have no idea and its driving me crazy! I don't think it's Hiro's father though because Linderman always remains unseen.

I think Linderman is either Hiro's father,or Claires adopted fater!

I dont think Linderman is Hiros father, I think Hiro would have kown... No I think Linderman will be a key character soon enough and possibly as some people have been suggestiong Claires father

I would just like to point out something! He's not Hiro's father! Linderman seems to be very powerful but it is very hard to pin down who he is! Hiro's father is a simple owner of the large company Hiro worked at: Yamagato Industries. WE see him working there in episode one. Linderman is defintily not Hiro's father. Pay more attention! PS. Claire's father is Nathan Petrelli obviously if you haven't being payed attention.

I checked the internet movie database cast of characters and Hiro's father is listed as Mr. Nakumura, not Mr. Linderman. George Takei(Mr. Nakumura,) is only listed as filming one episode of the show, so I think that rules him out as being Mr. Linderman. I don't think we're going to see Linderman for quite some time, very close to the nitty gritty.
