formidable

adjective·/FOR-mih-duh-buhl/

So strong, large, or impressive that it inspires respect, awe, or a little fear. A formidable opponent is one to take seriously.

Formidable blends impressive with intimidating: it is admiration mixed with the sense that this is not to be taken lightly.

The traditional stress is on the first syllable (FOR-mih-duh-buhl), though for-MID-uh-buhl is also widely accepted.
