Menace means that the creature can't be blocked except by two or more creatures (CR 702.111b). This means a single blocker can never legally block a menace creature. However, every creature assigned to block it must individually satisfy all normal blocking restrictions.
Normal blocking legality rules (CR 509.1b) require each potential blocker to be able to block that specific attacker — for example, a creature with flying can only be blocked by creatures with flying or reach. Menace does not override these individual restrictions; it simply adds an additional requirement that at least two legal blockers must be declared.
So if a defending player only has one creature that could otherwise legally block the menace creature, they cannot block at all — not even with that one creature. Both (or more) declared blockers must each be individually legal.
Example: Your opponent attacks with a 3/3 with menace and flying. The defending player has a 1/1 with flying and a 1/1 with no evasion. They cannot block: the ground creature can't block a flying attacker, so only one legal blocker exists, which is insufficient for menace. The 3/3 gets through unblocked.
In short, menace raises the minimum number of blockers to two, but it does not relax any of the standard individual blocking restrictions found in CR 509.1b.
