Bestia Oscura
The Dark Beast has the same superhuman abilities and intelligence as the main Marvel Universe's Beast before he underwent his secondary mutation. However, Dark Beast was not physically as powerful as his counterpart was in the normal Marvel continuity as he did not train on a regular basis, also being hampered by the fact that he is 20 years older than the main universe's Beast. As well as being physically weaker, while as intelligent as his counterpart, "normal" Beast seems to possess a larger spectrum of knowledge, as evidenced when Dark Beast was infiltrating the X-Men and became annoyed at the amount of knowledge the X-Men expected him to possess. This is due to Dark Beast specializing in genetics, while 616 Beast maintained study in multiple fields, with the result that Dark Beast has more specialized knowledge on that topic where "normal" Beast is more adaptable.
