Psychic powers need not manifest ostentatiously. They can work subtly, and in fact often do in a nascent psyker.White Haven wrote:If anything, Titus is a manifesting Untouchable, as not once does he use a psychic power of any kind. I realize that the lolflashy visuals on Fury could be construed that way, but given that Leandros is watching him like a hawk and nobody once mentions it, that can be discounted as artistic license for space marines kicking ass. Given that Untouchables are essentially the polar opposite of psykers...
It's unlikely that any untouchable could become a Captain of an entire company of Space Marines. Untouchables are by their very nature un-charismatic and repulsive - almost all humans are low-level psykers, and since untouchables are anathema to psykers, most people naturally find them unpleasant to be around.
