In the recent Thor trailers, you may have caught a glimpse of Tadanobu Asano, who plays Hogun the Grim (one of the Warriors Three.) In the Thor comics, The Warriors Three are Thor’s allies. As part of the trio, Hogun is described as excellent overall battlefield warrior, a collector of weaponry and often the voice of reason for the Warriors Three. If he is injured, his body is able to heal itself with superhuman speed and efficiency. You can see trio standing together behind Thor is Trailer #2.
