Mars square Pluto (orb 1.2°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Mars in Leo in House 2 brings action, courage, competition, and effort into House 2 (resources, values, and security), with Leo style (presence, pride, creation, and the wish to be seen); Pluto in Taurus in House 11 brings crisis, power, survival, and regeneration into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance).
Concrete friction: this aspect creates friction between Mars (action, courage, competition, and effort) and Pluto's crisis instinct: pressure can become domination, fear, or destructive escalation unless it receives a clear outlet. House 2 (resources, values, and security) is in friction with House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
